EXAMPLE 3-27:
//Clear PORTC to a known state
//Set the least significant bit to 1 so that it can be
//shifted through
//Clear the PORTA register to a known state
//Configure PORTC's ANALOG/DIGITAL pins as all Digital
//Configure PORTC pins as all output
//i.e. 1 = Input, 0 = Output
//Configure PORTA bit RA0 as Digital input
//Configure Timer0 to overflow every 5mS
//Select a 1:32 prescaler
//Initialize the direction flag to shift bits from right-to-left
//(i.e. 0 = Shift PORTC bits from right-to-left
//
//Initialize LED_Output to all zeros
//Configure for RA2 Interrupt-On-Change
